MILDREN, OF PONCA CITY, OKLAH01VIA,'A1\TD ONE-HALF TO W. E. COX, OFTIN-- FIELD, KANSAS FORGE-FEED LUBRrcAroR Application filed February Theinvention relates to lubricators and more particularly to devices forautomatically and positively supplying oil to moving parts of machinery,such as steamand gas engine cylinders, compression and pump cylinders,bearings of every description and moving parts to minimize the frictionand wear.

The invention contemplates a container for the oil, a sight gage, aprimary pump for delivering oil to the sight gage, so that the feed andthe amount of oil supplied may be observed, and an auxiliary ordispensing pump for forcing the oil to the required point of use.

lVhile the drawings illustrate a preferred embodiment of the invention,it is to be understood that in adapting the means to meet specific needsand requirements, the design may be Varied and such other changes in theminor details of construction may be resorted to within the scope of theinvention as claimed, without departing from the spirit thereof.

For a full understanding of the invention and the merits thereof,reference is to be had to the following description and the drawingshereto attached, in which,-

Figure 1 is a top plan View of a lubricator, embodying the invention,the cover of the oil container being removed,

v Figure 2 is a vertical sectional view on the line 22 of Figure 1,looking in the direction of the arrows, the cover and sight feed being Vin place,

Figure 3 is an elevational view of the lubricator, and r Figure 4 is adetail view of the arm applied to the pump operating rockshaft.

Corresponding and like parts are referred to in the followingdescription and designated in the several views of the drawings by likereference characters.

The container for the oil is designated by the numeral 1 and may be ofany capacity,

sists of a cylinder and a plunger, the cyLinders being disposed inparallelrelation and connected to a wall of the container. The primarypump is designated by the numeral 8 and the auxiliary, or dispensingpump by the numeral 9. The cylinder of the primary pump 8 is provided ina sidewith a feed opening 10. A pipe 11 projects vertically from thecylinder of the dispensing pump 9 and passes through the cover 2 andterminates within the lower portion of the casing f the sight feed. Apipe 12 projects up-- wardly from an end of the cylinder of'the prlmarypump 8 and its upper end passesthrough thecover 2, and extends into theupper portion of the casing 5 and is recurved and terminates in verticalline withthe pipe 11 from which it is spaced a suitable distance toadmit of ready observation of the oil discharging from the upperdelivery end of the pipe 12 into the upperjreceiving end of the pipe'11. The pump '8 includes a plunger 8? and the pump 9 embodies a plunger9' and these plungers operate in suitable guides 13 secured to the Wallof the container opposite that to-which the pumpicylinders'areconnected.

A yoke 14 connects the plungers 8 and9 for simultaneous movement andthis yoke terminates inpintles 15 which enter slots 16 in the free endsof arms 17 attached to a rock shaft 18 mounted in opposite sides of thecontainer 1 and having an end extended and provided with an arm 19 whichmay be connected in any convenientand determinate way with a moving partfor operating the device. The operating arm 19 is provided in its lengthwith a plurality of openings 20, whereby the operating part may beadjustably connected thereto. V I

In practice, the container 1 is supplied with oil and the auxiliary, ordispensing pump is connected by means of a pipe 21 with the part, orparts to .be lubricated. The rock shaft 18 is oscillated and through theconnections shown and described: imparts a reciprocatory' movement tothe pump plungers 8 and 9. Upon the out-stroke of the plu-ngers, theopening 10 and the lower endof the pipe ll-are uncovered and oil passesfrom theconta-iner 1 tothe cylinder of the pump 8 through the feedopening lOandany oil that rmay have been supplied to the pipe 11 passestherefrom into the cylinder of the; dispensing pump. ,9, Upon theforward stroke of the plungers 8 and 9 oil is discharged from the pump8' and pipe l2'into the pipe ll'and from the pump 9- mm the distributingpipe 21,-it being assumed that the pipe 12 and cylinder of the pump-8-have been previously charged. The oil forced from the cylinder of thedispensing pump 9' container, the auxiliary pump-having an outletexternally of the container and avertically disposed inlet pipe withinthe container and open at its upper end, said primary pump: having inletwithin the container and an outlet pipe extending upwardly fromitscylinder and terminating 'in a curved upper end ort'i'on disposed overthe open upper end yoke extending transversely between andtsecured tosaid plungers and having its end portions provided with pintles, a rockshaft rota-tably carried by walls of'the container and extending abovesaid plungers in crossed relation thereto with one end projectingoutwardly from the container, depending arms ad-justably carried by saidshaft and extending radially therefromand having slotted lower free endportions straddling the pi-n-tles of said yoke, and an actuating handlecarried by, the outer end portion of said shaft.
